Pre-study relevant baseline characteristics (n=16)a of volunteers in the dual-label stable isotope calcium bioavailability studyb
| Characteristics | Value |
|---|---|
| Age (y) | 35±7 (25-45) |
| BMIc | 24±2.4 (19-32) |
| Serum 25(OH)D (ng/mL)d | 35±6.4 |
| Energy intake (kcal/d) | 1,357±403 (739-1,995) |
| Protein intake (g/d) | 69±5 (53-96) |
| Fat intake (g/d) | 41±17 (13-64) |
| Carbohydrate intake (g/d) | 166±68 (15-287) |
| Calcium intake (mg/d) | 695±442 (203-1,726) |
a
All values are mean±standard deviation with ranges in parentheses.
b
Nutrient values were calculated from 2 days food-intake diaries at baseline. There was no substantial change in dietary intake of nutrients or calcium during the study.
c
BMI=body mass index; calculated as kg/m2.
d
25(OH)D=25-hydroxyvitamin D. To convert ng/mL 25(OH)D to nmol/L, multiply by 2.496.
